The present invention relates to new watersoluble soaps, being compositions consisting of neutral or acid soapy washing agents and moth proofing agents having an aflinity for wool, said soaps being suitable for cleaning and rendering moth-proof wool, feathers, hair and the like in one and the same process.

We mean by neutral washing agents, for instance, the neutral alkali salts of palmitic, stearic, oleic acids. as contained in the usual soaps and by acid washing agents, the alkyl esters of sulfurized castor oil or of sulfurized oleic acid or oleyl-methylamlno-methane or similar washing agents resistant to acid reaction. We mean by moth proofing agents having afllnity for W001 the salts of quaternary phosphonium bases such as triphenyl-dichloro-benzyl-phosphonium chloride, salts' of hydrofluoric acid, hydro-silico-fluoric acid, hydro-fluorotanic acid, boro-fluoro-acetic acid, selenic acid, selenious acid or the free acids, aromatic hydroxy-carboxylic acids or their halogenated substitution compounds, and aryl-sulfamides, in which hydrogen atoms connected to the nitrogen atom of the amino group can be replaced by alkyl or aryl radicals.

The new compositions are obtainable in a known manner by incorporating into such neutral or acid washing agents, moth-proofing agents as above described.

The new compositions thus produced are colorless or slightly colored in the dry state, being and are soluble in water. All these soaps, in the form of lumps, powders, pastes or solutions, can be used 'for simultaneously cleaning and mothprooflng materials liable to attack by moths. The specific moth-proofing agent incorporated with the soapy component depends on the chemical behavior of said soapy component, which is more fully, described hereafter. Thus, when ,using as mothproofing agent the free selenic acid or selenious acid itself or acid salts of hydrofluoric acid or hydro-fluo-silicic acid or their soluble salts or suitable mixtures of the above. agents, a soapy component resistant to the acid reaction is required, for example, oleyl methyl aminoethane sulfonic acid, while the salts of quaternary phosphonium bases may be combined with the neutral alkali salts of palmitic, stearic, oleic acid and the like.

The following examples will illustrate our invention but without limiting it thereto. The

parts are by weight.

Example 1.-To 80 parts of a neutral or acid sulfonic acid or oleyl-hydroxy-ethane-sulfonic acid-.(sodium salt) soap 20 parts of triphenyl-dichloro-benzylphosphonium chloride are added, and the whole is intimately mixed. Instead of the triphenyl-dichloro-benzyl-phosphonium chloride also other salts of quaternary phosphonium bases can be used either alone or mixed with another one, the quantity depending on the efficacy of selected compounds. 10 parts of this special soap dissolved inl000 parts of water are used for washing woolen material in the customary manner at about 40 to 50 C. The material treated in such a manner is cleaned and moth-proofed at the same time.

Example 2.--To 80 parts of oleyl-methylamino-ethane-sulfonic acid 20 parts of sodiumsilico-fluoride are added, and the whole is intimately mixed.

Instead of sodium-silico-fiuoride other acid moth-proofing agents such as potassium-hydrofluoride, boro-fluoro-acetic acid,,acid salts of selenic acid can be used. Wool, hair, feathers and the like treat-ed with such a soap in a. solution or 10 parts of this special soap in 1000 parts of water will be cleaned and moth-proofed at the same time.

Example 3.-80 parts of oleyl-hydroxy-ethanesulfonic acid in the form of its sodium salt and 20 parts of dichloro-salicylic acid are intimately mixed.

Wool treated in a solution of 20 parts of such a soap in 1000 parts of water is cleaned and renderedmoth-proof in this way.

Example 4.--20 parts of bis-1.3-dichloro-benzol-i-sulfo-1.3-phenylene-diamide are emulsified in 80 parts of the alkyl ester of sulfurized castor oil.

Wool treated in a solution of 20 parts of such a soap in 1000 parts of water at 60 C. is cleaned and rendered moth-proof at the same time.

A mixture of different soaps may be applied, and the process may be varied within wide limits according to requirements.

It will be, of course, understood that when the new process is applied to fur, care must be taken not to attack the skin.

We claim:

1. A mothproofing detergent composition consisting essentially 10f a neutral soapy washing agent in preponderating proportion, and a watersoluble salt of an organic quaternary phosphoni um base, said composition being at the most only slightly colored in the dry state, being soluble in water, and being adapted for simultaneously cleaning and rendering moth-proof wool, feathers, hair and like materials.

2. A nrothp'moflng detergent composition consisting essentially of a. neutral soapy washing agent selected from the group consisting of oleic,

palmitlc and stearic acid water-soluble soaps in preponderating proportion, and triphenyl-dlchloro-benzyl-phosphonium chloride, said com- Y rials.
